Hi,

I followed these steps to install rstan: [RStan Getting Started · stan-dev/rstan Wiki · GitHub](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started)

Including these steps: [Configuring C Toolchain for Windows · stan-dev/rstan Wiki · GitHub](https://github.com/stan-dev/rstan/wiki/Configuring-C---Toolchain-for-Windows)

Everything looked ok with no errors until I ran  
install.packages(“rstan”, repos = “[https://cloud.r-project.org/](https://cloud.r-project.org/)”, dependencies = TRUE)

and received this error:

```
* installing *source* package 'rstan' ...
** package 'rstan' successfully unpacked and MD5 sums checked
** libs

*** arch - i386
Error in .shlib_internal(args) : 
  C++14 standard requested but CXX14 is not defined

```

Can you advise what the issue is?

My makevars.win file looks like

CXX14FLAGS += -mtune=native -O3 -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2

I have r version 3.5.2 and Rtools version 3.5.0.4. I can install a package from source.

I also tried installing from cran and received the same errror.

Thank you

</div>

Can you try running:

```r
cat("CXX14 = $(BINPREF)g++ -std=c++1y",
    file = "~/.R/Makevars.win", sep = "\n", append = TRUE)

```

Then restart R and try the install again?

After running that I received this warning message:

```
Warning message:

```

But it did successfully install 2.21.2

Thank you!

I have a question (not sure if this is the right place to post but the topic seems related). After installing RStan I tried to verify my installation by running:

example(stan\_model, package = “rstan”, run.dontrun = TRUE)

After doing so I then got this error message:

Compilation ERROR, function(s)/method(s) not created!  
Error in compileCode(f, code, language = language, verbose = verbose) :  
C:/RBuildTools/4.0/mingw64/bin/…/lib/gcc/x86\_64-w64-mingw32/8.3.0/…/…/…/…/x86\_64-w64-mingw32/bin/ld.exe: file6834192127b1.o:file6834192127b1.cpp:(.text$\_ZN3tbb8internal26task\_scheduler\_observer\_v3D1Ev[\_ZN3tbb8internal26task\_scheduler\_observer\_v3D1Ev]+0x14): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:/RBuildTools/4.0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: file6834192127b1.o:file6834192127b1.cpp:(.text$_ZN3tbb8internal26task_scheduler_observer_v3D0Ev[_ZN3tbb8internal26task_scheduler_observer_v3D0Ev]+0x1c): undefined reference to `tbb::internal::task\_scheduler\_observer\_v3::observe(bool)'C:/RBuildTools/4.0/mingw64/bin/…/lib/gcc/x86\_64-w64-mingw32/8.3.0/…/…/…/…/x86\_64-w64-mingw32/bin/ld.exe: file6834192127b1.o:file6834192127b1.cpp:(.text$\_ZN3tbb10interface623task\_scheduler\_observerD0Ev[\_ZN3tbb10interface623task\_scheduler\_observerD0Ev]+0x1c): undefined reference to `tbb::internal::t

So I restarted R and reinstalled RStan and Stan headers by entering:

Sys.setenv(MAKEFLAGS = paste0("-j",parallel::detectCores()))

install.packages(c(“StanHeaders”,“rstan”),type=“source”)

However, I still get the same error message when I try to verify my RStan installation. What should I do?

I basically followed the steps outlined in: [RStan Getting Started · stan-dev/rstan Wiki · GitHub](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started)

I’m having the same error as above, also using R version 4.2.0. Any resolution here?

Can you try using the preview of the next rstan version:

```r
remove.packages(c("StanHeaders", "rstan"))
install.packages("StanHeaders", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))
install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))

```

That worked! Thanks for your help. For reference for others, my Makevars.win file looks like this:

```nohighlight
CXX14FLAGS += -mtune=native -O3 -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2

CXX14 = $(BINPREF)g++ -std=c++1y

```

Also, using the following line can help you access your Makevars.win file:

```nohighlight
usethis::edit_r_makevars()

```

</div>

I entered the code you sent through, then:

example(stan\_model, package = “rstan”, run.dontrun = TRUE)

Now I get this error:

Error: unexpected input in “example(stan\_model, package = “”

Any ideas?

The quotation marks get changed by discourse when they’re posted as text to the forum, you need to either change them or you can copy the code block below:

```nohighlight
example(stan_model, package = "rstan", run.dontrun = TRUE)

```

My bad. Thank you, it is working now.
